Integrated amp for Gallo Reference 3

I've been wanting to upgrade my current integrated amp and was wondering if anyone had any insight into which integrated amp would pair well with the Gallos. My thoughts were Musical Fidelity's A5, or the Plinius 9200 and possibly the krell 400xi.
Any other suggestions. Anyone currently running an integrated amp with their gallos that rocks their world?

Thanks in advance,

J.
